ADOLFO FORTUNATO PANDO, OF BUENOS AYRES, ARGENTINA.

HARVESTER.

Specification of Letters Patent.

Application filed May 22, 1908.

Patented Dec. 6, 1910.

Serial No. 434,323.

To all whom it may concern:

Be it known that I, ADoLro FoRruNATo PANDO, citizen of Argentina, andresident of No. 829, Calle de Cangallo, in the city of Buenos Ayres,Argentina, engineer, have invented certain new and useful Improvementsin Harvesters, of which the following is a specification.

This invention relates to improvements in harvesters especially adaptedfor use in harvesting corn, sugar cane, maize and any kind of crophaving long and large stalks.

The invention is designed to cut the stalks close to the ground andconvey the severed portions of the stalks to the bundler which may beoperated at desired times to release a quantity of the stalks when thebundler has been filled and deposit the stalks upon the ground so thatthey can be shocked.

The invention will be more fully described in connection with theaccompanying drawings and will be more particularly pointed out andascertained in and by the appended claims.

In the drawings :Figure 1 is a side elevation of a harvester embodyingthe main features of my invention. Fig. 2 is a plan view thereof. Fig. 3is a longitudinal sectional view on line O-N of Fig. 2. Fig. 4: is alongitudinal sectional view on line L-M of Fig. 2. Fig. 5 is afragmentary elevational view of one of the conveyers looking in thedirection of the arrows 5 of Fig. 2 and illustrating the constructionshown in Fig. 3 on an enlarged scale. Fig. 6 is a plan view of the partsshown in Fig. 5.

Like numerals of reference designate similar parts throughout thedifierent figures of the drawings.

The improved harvester according to my invention is mounted upon an axle2 sup ported by wheels 1, and 2ft designates the attachment to which thehorse may be hitched to draw the harvester. The shaft 36 is providedwith a gear 18 which meshes with a gear 36L on the aXle 2 and said shaft36 also carries a sprocket wheel 36 for driving a sprocket chain 15. Ashaft 17 is provided with a sprocket wheel 20 over, which the sprocketchain 15 is trained and said shaft 17 is also provided with a sprocketwheel which drives a shaft 17 by means of a sprocket chain 30 andsprocket wheel 21, the latter being mounted on the shaft 17 The shafts17, and 17 carry at their opposite ends sprocket wheels 16 over whichconveyer chains 7 are trained and which chains extend over idlersprocket wheels 38 mounted on shafts'37. Shafts 29, mounted in bearings40 carry idlers 9 which maintain central portions of the conveyer chainsin a prescribed line of movement, as will hereinafter more fully appear.It will be seen from the foregoing that pairs of conveyer chains areprovided in superposed relation with the pairs laterally disposed withrespect to each other and traveling in parallel relation.

Each chain is provided with a plurality of movably mounted or hingedfingers 6 arranged to be moved or shifted transversely with respect tothe line of travel of the chain. Said fingers 6 are movably mounted at 8upon said chain. Said fingers 6 may be formed of an integral length ofwires bent in U-form to constitute the body of the finger and with itsterminals bent at right angles to form hinged portions for connectionwith the chain.

In the arrangement shown the conveyer chains are actuated in a manner tocause their uppermost lengths to travel in a direction reverse to thedirection of movement of the harvester while the lower lengths of thechains travel in the same direction as the harvester does. The purposeof the finger 6 is to engage the stalks and convey them rearwardly inthe harvester and, obviously, reversely acting or oppositely travelingthe fingers could not perform this function. Therefore according to myinvention means are provided for throwing those fingers travelingreversely with respect to the line of movement of the harvester intooperative relation and convey the stalks rearwardly and maintainingthose fingers which travel in the same direction as the harvester out ofoperative relation with the stalk. In the construction shown said meansalso serve to maintain the fingers 6 in an operative position.

In the specific embodiment of the invention herein shown shields 13 areprovided at each side of the machine and which extend throughout theline of travel of the chains and preferably slightly beyond the same atboth ends. Said shields 13 are arranged in parallel relation at thefront of the harvester and approximately half way of their length and attheir rear ends said shieldsconverge with respect to each other asclearly shown in Fig. 2. The disposition of the idlers 9 is such as tomaintain the chains in substantially parallel relation with said shields13. The upper marginal portions 41 of said shields 13 serve to supportthe fingers 6 in a horizontal position while the same are conveying thestalks rcarwardly and the marginal portion 41 of said shields 13terminates, adjacent the ends of the chains, in cam portions 42 and 43respectively. Guide boards 23 are arranged in parallel relation with theshields 13 and form therewith a passageway for the stalk. \Vhen thefingers 6 reach the cam port-ions 43 they are thrown upwardly asindicated at a, Fig. 5, into a position at right angles to thehorizontal. A guide board or guard 10 is disposed in vertical alinementwith the shields 13 and is spaced apart therefrom to form an openpassage 44 for the fingers 6. The fingers 6 therefore are conveyed inhorizontal position longitudinally through the machine, their verticalmovement being limited through the lower margin 45 of the guard 10 andthe upper margin. 41 of the shield 13. In the proximity of the camportion 42 and 43 respectively the guard 10 recedes, as indicated at 46,and extends at 47 in parallel relation with the shields 13. It will beunderstood that the foregoing arrangement is provided for the fingers ofeach conveyer chain. The guard 10 extends downwardly and forwardly fromthe part 47 as indicated at 48 in a manner to guide the outer ends ofthe fingers until they have passed over the sprocket wheel 38 and into avertical position as indicated at 7). The fingers will normally remainin this position during its travel toward the forward end of theharvester and lie back of the shields 13 so as to be completely out ofoperative relation with respect to the stalk. The construction of theguard 10 at the forward end of conveyer chain is substantially the sameas at the rearward end thereof and as the fingers approach the forwardend they pass between the cam portions 42 and portion 47 lying in aplane transverse to the axis of the shaft 17 until they reach the camportions 49 of guard 10. The cam portion 49 shifts the fingers throughan arc of 90 and into the horizontal position shown. Vhen the fingersengage the cam portion 49 they ride between the same and the camportions 42 which latter slope downwardly to the sunortm mar in 41 toraduall ll a, a b

bring the fingers into an operative position i with respect to thestalks.

I11 each of the lateral passage-ways formed by the shields 13 and guard10 on the inside and the guide-boards 23 on the outside, there areprovided horizontally disposed circular saws 4 which are operated by aworm 26 and worm wheel 27, the latter being mounted on the axle 2.Guides 3 may be provided to engage the stalks laterally in a manner topermit the saws to act upon the stalks. A platform 5 extends rearwardlyfrom each saw 4 to support the stalks as they are being conveyedreairwardly in the harvester by the fingers 6.

The superposed arrangement of fingers serves effectively to maintain thestalks in a substantially vertical position as the same are conveyedrearwardly upon the platform 5.

In harvesting crops such as corn, maize, sugar cane and the like, thestalks are usuallvshocked on the field and it is one of the objects ofmy invention to provide a bundler for collecting the stalks as the sameare conveyed rearwardly in the harvester and carry the stalks untilenough has been bundled to form a shock and thereafter dump the stalksupon the field. As shown the,

upper area of greater receiving capacity than the lower area toaccommodate for the leaves.

Means are provided for opening the racks 11 to dump the bundles ofstalks collected therein and as shown said means may consist of a lever22 pivoted at 32 and connected by a link with a lever 50 pivoted at 33.The lever 50 may be connected with arms 51 which latter are connectedwith arms 35 whereby the racks 11 may be opened and closed. A seat 25may be provided for the operator.

I claim 1. In a harvester for corn and the like the combination of guideboards, shields in opposition to said guide boards and forming passageways for the stalks in coaction with said guide-boards, juxtaposed pairsof superposed conveying chains, two of said superposed chains beingadjacent each of said passage ways, wheels rotating about horizontalaxes supporting and driving said chains, a plurality of fingers movablymounted on each of said chains, guards in superposition with regard tosaid shields, said guards and shields being provided with cam portionsadapted to shift said fingers into and out of said passage ways.

2. In a harvester for corn and the like the combination of guide boards,shields in opposition to said guide boards and forming independentpassage ways for the stalks in coaction with said guide boards,juxtaposed pairs of superposed conveying chains, wheels rotating abouthorizontal axes supporting and driving said chains, a plurality offingers mounted movably on each of said chains, guards insuperpositionwith respect to said shields, said guards and shields beingadapted to guide said fingers in horizontal position through saidpassage ways.

3. In a harvester for corn and such like the combination of guide boardsdisposed at the sides of the harvester, shields in opposition to each ofsaid guide boards and forming independent passageways for the stalks incoaction with said guide boards, platforms at the bottom of said ways,said passage ways being parallel to each other at the front end of theharvester and leading into each other toward the rear thereof,

conveying chains adjacent said passage ways, a plurality of fingersmovably mounted on each of said chains and means for defleeting saidchains from the parallel portion of said passage Ways into theconverging portion thereof.

In testimony whereof I affix my signature in presence of two witnesses.
